Using the given scale, 0.5 inch on the drawing represents 10 feet in real life. Therefore, 1 inch on the drawing represents 20 feet in real life (multiply both sides by 2).
To find the actual length of the park, we can use the proportion:
1 inch on drawing / 20 feet actual length = 4.5 inches on drawing / x feet actual length
(where x is the actual length we want to find)
Cross-multiplying, we get:
1 inch on drawing * x feet actual length = 20 feet actual length * 4.5 inches on drawing
Simplifying:
x = (20 feet * 4.5 inches) / 1 inch = 90 feet
Therefore, the actual length of the park is 90 feet.
